Inspection and Test Plan for Method Statement: Installation of Internal uPVC Soil, Waste and Vent (DWV) Piping Networks

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 18 Jul 2026 Rev. 00 2 views
About this ITP: This ITP defines inspections and tests for uPVC DWV systems from material receipt to final testing, including hold points for anchors, jointing, slopes, cleanouts, and firestopping.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To ensure installed DWV systems meet standards, project specs, and functional performance for leak tightness and self-cleansing gradients.

Who uses this inspection and test plan

Contractor supervisors and QA/QC, Engineer/Consultant representatives, and third-party inspectors where specified.

When this ITP is prepared and submitted

From material delivery through installation, curing, pressure testing, and final acceptance.

Who receives or approves this ITP

Engineer/Consultant for review and approval.

Inspection scope

Covers materials, anchors/hangers, pipe preparation and jointing, gradient/alignment, cleanouts, firestopping, and leak testing.

Typical hold, witness, and review points

Anchor layout; first-of-kind jointing and branch configuration; start and completion of water/air tests; firestopping installations.

Typical inspection records

Material inspections, anchor tests, jointing checklists, slope sheets, cleanout logs, firestop reports, test certificates, and as-builts.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Material receipt and identification Verify standards, sizes, markings; review COC and SDS Conformity to BS EN 1329-1/ASTM D2665; no damage/warping; correct batches logged Contractor QA/QC; Witness by Engineer Material inspection report, photos
Anchor/hanger layout and installation Check spacing, edge distances, embedment, torque Per manufacturer data and project design; corrosion class correct Contractor; Witness by Engineer Anchor/hanger inspection checklist, torque log
Anchor proof load test (if required) Apply proof load (e.g., 1.5× service load for 15 s) to sample anchors [Verify] No pull-out or displacement >1 mm; no substrate cracking Contractor with third-party if specified; Witness by Engineer Pull test certificates
Pipe cutting/deburring/chamfer Visual and measurement check Square cuts; chamfer 10–15°; edges deburred; cleanliness verified Contractor In-process QC checklist
Solvent cement jointing Check primer use (if required), cement coverage, insertion depth, alignment Full 360° bond; correct insertion depth (−0/+3 mm); uniform bead; no voids Contractor; Witness first 10 joints per shift by QA/QC Jointing inspection sheet; batch log
Slope and alignment verification Laser/level checks every 2–3 m and at mid-spans Continuous fall; slope within ±0.2% or ±3 mm/m; no sag/backfall Contractor QA/QC; Witness by Engineer as required Slope verification sheet; photos
Branch fittings and angle compliance Visual configuration check 45° wyes/combination fittings used; long-sweep bends; no short 90° on horizontal-to-horizontal Contractor; Witness by Engineer for first-of-kind Inspection checklist; photos
Cleanouts (location and accessibility) Verify spacing and clearance; access panels installed Spacing ≤12–15 m on mains; clearance ≥450 mm; caps removable Contractor; Witness by Engineer Cleanout schedule and photos
Firestopping at penetrations Check against approved UL/ETA system detail System ID matches site conditions; correct sealant/collar; labeling complete Firestopping Specialist; Witness by Engineer/Third-party if required Firestop inspection report; photos
System test – water or air Water head test or low-pressure air test No leakage; no pressure/level drop per approved test regime [Verify] Contractor; Witness by Engineer Test certificates; gauge/manometer readings; photos
Final visual and functional checks Flush/visual inspection; check labels and as-builts Free flow; correct labeling; documentation complete Contractor; Witness by Engineer Final inspection report; punch list closeout

Frequently asked questions

Use the project-specified method. Many codes allow either: water head test (e.g., 1.5–3.0 m) or low-pressure air test (around 34.5 kPa). Always verify with the Engineer.

Only where required by the project or for critical supports. If required, test representative anchors to the specified proof load and document results.

Preferably after, unless the certified system permits pre-test installation. Coordinate sequence to avoid damaging the firestop material.
